If building from scratch you owe it to yourself to first hear this version ( gotta love simple & cheap! ).

Rarely mentioned ( apart from it's infamous lumpy FR response ) is how coherent sounding that simplistic network can be ( a result < IME > of all 3 drivers using the same polarity and the gentle crossover slopes employed ).

No doubt the massive presence peak ( at 6K ? ) will eventually drive you nuts > though I would first try mitigating it with an LCR notch strapped across the Le5-2 (s) terminals ( before trying a completely different network ).

I would recommend doing the crossover ...JBL S70 Alpha III which used those drivers but wisely crossed over the woofer. I acknowledge it is not pure 100 but the resultant midrange clarity should be better.

I opened up my L100 - just to reject a peak.. looks like they were recapped, take a look, not sure what they are but I’ll do a more thorough investigation in the futur. For now I plugged the ports from the inside, better bass control
